Store B sells each cell phone at
each
clearly, store A provides a better deal than B because the cost of 4 cell phones is less for Store A i.e.

AC and AB are tangents to circle O, meaning that the angles C and B are right angles of 90 degrees. Since a quadrilateral's internal angles must sum up to 360 degrees, this means that A + B + C + O = 360
70 + 90 + 90 + O = 360
O = 110 degrees.

Answer:

Step-by-step explanation:
Let
represent the amount of money he initially started with.
After he spent 20% on books, he will have
of his initial money left. We can represent this as
.
Following that, the boy spends 20% of the remainder of his money on food. Similarly, he will have
of the remainder of money he had left after he purchased the books. Therefore, he ends up with
of his money left.
Since we're given that he had $2,000 after all these transactions, we have the following equation:

Divide both sides by 0.64 to isolate and solve for
:

Therefore, the boy had $3,125 to begin with.
